  • Patent number: 11498533
    Abstract: There is presented a method for controlling an activation threshold of a safety system of a vehicle. The method comprises receiving map data from a remote data repository, said map data comprising a geographical location of a dynamic object located in a surrounding area of an expected path of the vehicle, determining a geographical location of the vehicle by means of a localization system of the vehicle, and lowering an activation threshold value of the safety system when the geographical location of the vehicle is within a predefined distance from the dynamic object. The presented method provides for an efficient means for preparing e.g. an emergency brake assist system of a vehicle in potentially critical situations.

  • Patent number: 10922968
    Abstract: A method for providing information about traffic regulations in a vehicle is disclosed. The method comprises identifying a road sign in a surrounding area of the vehicle (e.g. by means of a perception system of the vehicle). Further, the method comprises identifying a traffic regulation associated with the identified road sign, in a current jurisdiction of vehicle, and retrieving traffic regulation data comprising information about a set of predefined road signs and associated predefined traffic regulations in a predefined jurisdiction. Still further, the method comprises comparing the identified traffic regulation with the retrieved traffic regulation data in order to determine if the identified road sign is not comprised in the set of predefine road signs, or if the identified traffic regulation differs from the associated predefined traffic regulations.

  • Patent number: 9505360
    Abstract: Embodiments herein relate to an arrangement and method for improving the performance of a safety-critical vehicle actuator, in particular a safety-critical vehicle actuator powered directly or indirectly from a vehicle electrical system. The safety-critical vehicle actuator is arranged to, upon activation thereof, signal to an alternator of the vehicle to output a raised voltage for a pre-determined time period.
